In ye olden days your motherboard was made of cheese and was really just a place for the RAM to sleep; now you can't move inside a computer without bumping into dual-channels, PCI-express slots and random little surface-mounted chips with their own tiny fans.  ASUS have stepped up the game (if the game you're playing is "build a complicated circuitboard") with their P5E3 Deluxe WiFi-AP@n motherboard, which not only boasts such niceties as Intel's X38 chipset, Dual PCI Express 2.0 x16 lanes and support for DDR3 1800MHz dual-channel memory, but integrated 802.11N wireless and embedded Linux.
